摘要
在总结石英热发光特性的基础上,提出了应用石英热发光实验技术,诊断火灾后混凝土的烧伤程度,并应用于特大火灾的工程实践。结果表明,混凝土中的石英砂辉光曲线,客观地反映了混凝土经历的温度上限,该方法与混凝土微观结构受热破坏的微观结构研究和现有常规检测手段相结合,将对混凝土火灾损伤评估技术带来新的突破和发展。
The experiment technology of thermoluminescence of quartz is proposed to diagnose the fire damage degree of concrete and applied to the project practice of especially big fire based on summarizing thermoluminescence characteristics of quartz in this paper. The result indicates that the curves of quartz sand thermolumines objectively reflected the temperature upper limit of concrete experience. If this method is combined with the damaged research of concrete microscopic structure for being heated and the existing conventional examination methods, it will bring the new breakthrough and development to the appraisal technology of fire damage degree of concrete.
